C 104, L031306 (2021) S.M.Lenzi, A.Poves, A.O.Macchiavelli Shell model analysis of the B(E2, 2+ → 0+ values in the A=70, T=1 triplet 70Kr, 70Br, and 70Se NUCLEAR STRUCTURE 70Kr, 70Br, 70Se; calculated energies and matrix elements Mp(E2) for the first 2+ states in isospin T=1 triplet, and compared with recent experimental data from RIKEN reported in 2021Wi01 (PRL 126, 072501); calculated B(M1) strength from the 2+ to a hypothetical 1+ state to explain missing intensity of the 2+ γ ray; deduced that anomaly of B(E2) for 70Br may be due to the presence of an undetected 1+, isospin T=0 state below the yrast 2+, T=1 state, and no support for a shape change of 70Kr with respect to the other members of the isobaric multiplet. Calculations based on state-of-the-art large scale shell model using the JUN45 and JUN45+LNPS plus Coulomb interactions. Systematics of low-lying T=0 and T=1 states in A=58, 62, 66, 70 and 74 odd-odd nuclei relevant to the A=70 region, and compared with JUN45+LNPS shell model results.
